The scapular of the Most Blessed Trinity, commonly referred to as the white scapular, is associated with the Trinitarian order. The design of the white scapular dates back to January 28, 1198 when an angel appeared to the Spanish priest, John of Matha. The angel was wearing a white robe with a blue and red beam across his chest in the form of a cross, the vertical beam being red and the crossbeam blue. The scapular of the Most Blessed Trinity was first used to petition the ransom of captives, Christians taken prison by Muslims. In order to become invested in the Confraternity of the Blessed Trinity you must constantly wear this scapular and have it blessed by a priest as granted by the General of the Trinitarians.
